AI Technical Summary
The refractory material in the rising flue lining of the silver furnace is severely removed, blocking the flue gas channel, and is easily burned by high-temperature flue gas. The service life of the flue is short, which affects the system operating rate. Moreover, the smoke and dust on the furnace wall are fast, difficult to clean, and the flue gas channel is not smooth, resulting in poor control of the furnace pressure, resulting in a high smoke rate.
The silver furnace upslide is transformed into a cooling water jacket structure, using a vertical water jacket group and a horizontal water jacket group, connected by a three-way connection, and molten copper water castings are buried in the side walls of the water jacket and the three-way connection to form a stable cooling water jacket structure to allow smoke to condense and settle.
The modified device is easy to clean, extends the service life of the flue, improves the smoothness of the flue gas channel, reduces the smoke rate, slows down the speed of smoke tumor formation, and improves cooling efficiency.
